Embodiment
At large scale network management, be necessary management work is distributed to and carry out distribution process in the whole system, again result is gathered.Have a plurality of managers and exist in such environment, network management work also should be allocated to each management station according to certain managerial structure.This managerial structure can be a kind of structure that can reflect the network joint relation, also can be a kind of structure that reflects the hierarchical management relation, even can be a kind of structure that reflects distribution applications.By by keeper's intention or according to the principle that adopts identical management policy with some managed objects grouping merger, can simplify according to managerial structure is the work that different management stations divides management responsibility.
Therefore, adopt distributed management to have more advantage to a large-scale Network Management.
Adopt many NM servers in the distributed network management system provided by the invention, the network element that network management system can be managed constantly increases along with the increase of number of servers, can manage ultra-large network.Dilation process only needs to increase server and memory capacity, makes the network management system dilatation more level and smooth, has simplified engineering construction.
For making principle of the present invention, characteristic and advantage clearer, describe the present invention below in conjunction with specific embodiment.
Comprise many NM servers in the distributed network management system that the embodiment of the invention provides, these NM servers are arranged in the zones of different of network according to network topology structure and service conditions, the webmaster processing module that may cause handling bottleneck is deployed to different NM servers, and the service processes that all webmaster processing modules are provided carries out dispatching management.Bottleneck appears handling to avoid or to reduce.
The webmaster processing module that may cause handling bottleneck comprises: data acquisition module, performance management module, Configuration Manager, fault management module, accounting management module and safety management module.
From handling on the level, data acquisition module may become the processing bottleneck, and data acquisition module is owing to will carry out more conversion and calculating, and its processing procedure also may be a bottleneck.Data acquisition module will be done protocol conversion, become the understandable form of network management system to the data transaction of network element, also will operation such as analyze to data.
From operational angle, performance module may become bottleneck, because the performance data amount is big and have periodicity, each cycle all can report a certain amount of data, and the data volume that each cycle produces is all very huge.
Because the network element of managing in the distributed management system is more than the network element of separate unit server admin, Configuration Manager and fault management module also may become the processing bottleneck after network element rises to some.The distributed network management processing scheme also will be handled other bottleneck problems that the increase owing to the NE quantity upper limit causes, and therefore Configuration Manager and fault management module is distributed away.
Embodiment one
With reference to Fig. 4, a kind of distributed network management system that the embodiment of the invention provides, be provided with four NM servers, certainly configurable as required more multiserver, dispose different webmaster processing modules respectively in described four NM servers, as performance management module, Configuration Manager, fault management module, accounting management module and safety management module.
The unified scheduling of each NM server in the distributed network management system provided by the invention, collaborative work, at this, with one of in the NM server as major network pipe server, its deploy has common profiles and public management module, other NM servers are from NM server, describedly are provided with the webmaster processing module from NM server.For example, four NM servers are arranged in the distributed network management system that the embodiment of the invention provides, wherein a NM server is as main frame (Master), other three NM servers as slave (Slave1, Slave2, Slave3).The Master server is born control and is coordinated the responsibility of other Slave servers; In Master server deploy some public services, as name service, performance service, alerting service, configuration service etc., and all common profiles all are placed on the Master server;
The Slave server mainly is to share handling load, disposes the processing module that causes handling bottleneck, as performance management module, data acquisition module, Configuration Manager, fault management module.When bottleneck has appearred handling in some public services of Master server, some common service services and Business Processing can be deployed to separately on the Slave server.
Be provided with scheduling unit in the distributed network management system of the embodiment of the invention, be used for dispatching the service processes of each the webmaster processing module that is deployed in all NM servers; Particularly, the service arrangement that different webmaster processing modules are provided is in different processes, and the service that may cause handling the same class processing module of bottleneck provides is separated in the different processes, to avoid or to reduce the processing bottleneck.
Particularly, this scheduling unit is divided into two dimensions in computing, and a dimension is exactly that different Service Processing Modules is put in the different processes according to the classification of managing business; Another dimension is that same class is professional owing to handle bottleneck, according to certain principle service processing is separated in the different processes, just the multi-process mode of service processing.Utilize the characteristic and the advantage of distributed treatment, bottleneck occurs handling to avoid or to reduce.
This scheduling unit is supported two types migration, and a kind of is to be specifically responsible for the collection process migration of module from a station server of network element collection in the collection process of another station server.Another kind is with the business service process, as: configuration management and fault management service, move to another station server from a station server.Mostly latter event is to be used for from the Master server migration to the Slave server.
Because operation has a plurality of network element acquisition modules in the collection process, the corresponding network element of each acquisition module, these acquisition modules can be between the collection process in the same station server free migration, owing to relate to the migration of persistant data and the change of server access information, as: the change of visit IP address, so between the collection process on the different server, move acquisition module, need extra operation support.These extra operations mainly are to be used for visit information that the permanent message of acquisition module is moved to another station server and adjusted acquisition module from a station server, and just other modules will be when this acquisition module be communicated by letter, and its link information need adjust.The migration of business process mainly also is its persistant data information and visit information of migration.
This scheduling unit can independently be provided with, and also can be located in one of them NM server, but be arranged on the Master server usually, and GUI only discerns the Master server.
For each server is equipped with database and memory cell, be respectively applied for the data on each NM server of management in the distributed network management system of present embodiment.
Memory cell can adopt suitable storage medium as the case may be, is disk array as what adopt in the present embodiment, and disk array of the independent connection of described every station server is used for preserving respectively the data on each server.

Described name service module independent part is deployed in wherein NM server; Or
All dispose described name service functional module at every NM server, so that the addressable any NM server of client.
The distributed network management system of present embodiment disposes multiple servers, in order to make the GUI configuration simple, needs the otherness of shielding service position.Shield the otherness of service position by the name service.It is just passable that GUI only need be familiar with the server at name service place, thereby shielded the alternate position spike opposite sex of each service.The increase and decrease of subsequent server quantity and the migration of service between each server can not influence the access of GUI.
Distributed network management installation procedure interface support the user different collection service distribution to different servers, also support is different business service, as: configuration management and fault management service are deployed on the different servers.
Installation procedure is provided with situation to client's deployment and forms configuration file, and is stored on the Master server.The global service monitoring program starts different processes according to the deployment scenario information in this configuration file on different servers.The main program of global service monitoring program operates on the Master, and each Slave goes up operation its agency, and the agency is responsible for carrying out the instruction of global service monitoring program, as: start service, stop service, the report service operation is unusual etc.
Particularly, with reference to Fig. 5, except disposing acquisition module, also be deployed with performance management module and database on each Slave server.The performance data that acquisition module on this Slave server of performance data library storage on each Slave server is collected.Can adopt the multiple database design as previously mentioned, not repeat them here.
As shown in Figure 6, when there is the processing bottleneck in the Service Source on the Master server, some services can be put into separately on the Slave server, to alleviate the processing pressure of Master server.Provide malfunctioning module and configuration module process below from the Master server migration to the Slave server.
The Slave server is many after some, and the hardware resource that service needs can get more and more, and the processing of Master server can become bottleneck.Handle in the concrete scheme at distributed network management provided by the invention, fault management module and Configuration Manager etc. can be deployed on the Slave server.
Certainly, in specific implementation process, can not distinguish Master and Slave, Servers-all all has par.As the case may be, in each NM server, dispose corresponding webmaster processing module as required: performance management module, data acquisition module, Configuration Manager, fault management module, accounting management module and safety management module, and these webmaster processing modules are carried out unified coordination and administration.
Allow to exist a plurality of performance databasies in a system, on the processing node (can be that Master also can be Slave) of distributed network management system, if dispose data acquisition module on this node, this node will be disposed performance database so.
In addition, can select storage schemes such as SAN, and select to be fit to the database of SAN storage scheme, can not adopt many performance databasies in this case.
Realize the method for distributed network management in the embodiment of the invention, four NM servers are set in network management system, this method comprises:
According to network topology structure and service conditions, each webmaster processing module is deployed in described four NM servers; Particularly, may cause handling the webmaster processing module of bottleneck, as data acquisition module, performance management module, Configuration Manager, fault management module, accounting management module and safety management module etc., be deployed to described each NM server respectively, with reference among the figure at major network pipe server, its deploy has common profiles and public management module, other are configuration data acquisition module, performance management module, Configuration Manager, fault management module from the server, certainly also can be therein from the one or more administration modules of server configuration.
Scheduling is deployed in the service processes of each the webmaster processing module in all NM servers:
The service that different webmaster processing modules is provided is arranged on different processes, and the service that will cause handling the same class processing module of bottleneck provides is separated in the different processes.
In the embodiment of the invention, can increase NM server and memory space as required, can carry out smooth expansion to system, the basic step of dilatation is as follows:
Step S01: increase hardware newly, comprise the server and the corresponding array that increase newly.
Step S02: the hardware that initialization increases newly, and OMC software is installed in the above.
Step S03: the network that the server that increases newly is connected to the OMC place.
Step S04: the relevant information of the server that configuration increases newly on the Master server, as: the access to netwoks address information needs the server info of operation etc.By these information, Master just can manage the server that increases newly.
Step S05: by command mode or other triggering modes, as: gui interface etc., trigger Master to increasing the management of server newly, Master is responsible for starting with management and increases OMC service relevant on the server newly.
If the process in the server that increases newly is the service of gathering, do not rely between collection service and other business service, so increase the process of service newly other services there is not influence.If integrated in the server that increases newly is business service, business service need be come to other server migrations, and then affected service need only can be confined to the service of migration.The migration service process is carried out after server adds successfully.
In the embodiment of the invention, client is used the alternate position spike opposite sex of each business service of name service shielding by graphical user interface GUI.
Be provided with the name service module in the distributed network management system, be used to identify the NM server that service is provided, to shield an alternate position spike opposite sex of service.
Suppose that the name service arrangement is on the Master server.The deployment way of name service can be varied: can independent part be deployed in a wherein station server, as: be deployed on the Master server or Slave server on; Also can all be deployed with the name service on each machine, client can select a station server as access arbitrarily like this.
In the distributed network management scheme provided by the invention, the name service in the use CORBA communication mechanism shields the alternate position spike opposite sex of service.By name service registry service to CORBA, realized the circular of service position, other services can get access to the visit information of registration service from location-based service.Present embodiment can use the naming service mechanism of CORBA to realize the service position transparency, with convenient exploitation, deployment and the client's who serves connection.Also can use the other technologies scheme to realize the service position transparency, as: correlation techniques such as ICE, EJB.Adopt other technologies to realize the service position transparency, belong to known technology, no longer describe at this.
Be that example describes with the name service arrangement at the Master server below.
With reference to Fig. 7, suppose that client (GUI) wants the access fault service, and failed services is deployed on the Slave server.
For convenience of description, only provide the situation that has two-server among the figure, one as the Master server, and one as the Slave server.
Client (GUI) accessing step is as follows:
Step S11: client (GUI) is to the server at the name service request failed services place of Master server.
Step S12: client (GUI) gets access to the reference address of failed services on the position Slave server at failed services place.
Step S13: client (GUI) is initiated request to the server at failed services place.
Step S14: failed services is returned accordingly result to client GUI.
By above step, client (GUI) does not need to know the deployed position of each service, has shielded the alternate position spike opposite sex of service, has simplified the configuration of the visit information of client (GUI).
Embodiment two
Present embodiment and previous embodiment one are basic identical, and difference is: do not adopt multidatabase system, but adopt the intensive data storage, as: adopt the SAN storage scheme, and use an independent Database Systems example.
With reference to Fig. 8, adopt independently array and Database Systems example, its main purpose is a processing bottleneck problem of concentrating IO in order to solve.If adopt suitable data storehouse technology and similar SAN memory technology, concentrating IO to handle bottleneck will no longer exist.At this moment, suggestion is adopted centralized stores and is used single sets of data storehouse system.If Database Systems are supported the multiple database example, can be divided into a plurality of database instances as required in the system of so single sets of data storehouse.As: in the ASE of Sybase Database Systems, can be divided into a plurality of databases (database) as required.
Top line has mainly been expressed the data flow between server and the array.Net connection between the server is with consistent shown in Fig. 4, i.e. server independent array, and server importance is had any different.
Database server (Database Server) is connected with array, and main purpose is a data of database in the managing array.Other servers (Master and each Slave) are connected with array, and main purpose is the data of storage system in running, as: service configuration data and running data etc.
In order to reduce the line that server is connected with array, can between array and server, increase the exchange layer, as: optical fiber switch.
For reliability is provided, can dispose two memory transactions equipment, make biplane.
The storage of concentrating is beneficial to data and uses and manage concentratedly.As: be beneficial to the correlation inquiry that utilizes database mechanisms to realize data, be beneficial to the contrast between a plurality of data, be beneficial to centralized backup and recovery, be beneficial to and concentrate dilatation etc.
Can increase the managerial ability of a cover OMC by increasing server and memory space mode equally.Use this embodiment, the function of previous embodiment does not reduce or weakens.
For reliability is provided, can dispose two memory transactions equipment, make biplane.As shown in Figure 9, between described data storage cell and described each NM server, the memory transactions device is set, is used to realize between described data storage cell and described each NM server and the exchanges data between the NM server.
Embodiment three
And the embodiment difference of front is: the status between each server does not have difference.No longer distinguish main Master between each server and from Slave.Server is a platform of operation service.Therefore, service can be as required, as load reason and hardware fault reason etc., and free migration and moving between each server.Which station server service specifically operates on is unfixed.Client will be visited these services, must have an entity to inform the reference address of these services, and this entity is exactly the service access telegon.
The service access telegon is mainly managed the positional information of each service, the management service change in location, and accept the position enquiring of client (Client) to service.The client comprises GUI client and other services, and these services not only externally provide service, also visit other services.Service access telegon and the responsibility basically identical of naming service.If client is not carried out persistence service access information (service reference information), then can use name service to substitute, if persistence service access information, then need to possess the service access telegon of visit information Notification of Changes.
Be that example is introduced the service access coordinator function with the service of GUI client-access below, the process of client access service is identical therewith not to be repeated them here.
With reference to Figure 10, during GUI client-access server, can select a server arbitrarily as access point.All be deployed with the service access telegon on each server.The main purpose of service access telegon is to finish GUI client access-in management and shielding service position difference.
When the GUI client needed access services, the GUI client was obtained the positional information of service to the service access telegon; The service access telegon returns the positional information of the service that needs and gives described GUI client, and described GUI client is according to the address access services that obtains.
If GUI client persistence the visit information of service, GUI will be responsible for more service access information, as: restart after the GUI client or the service access failure after, obtain service access information again one time; Receive the service access information change notifying of service access telegon etc.
With reference to Figure 11, the service access telegon can be deployed to a station server separately.
The service access telegon is deployed to separately on the cover server, and making the GUI client is the reference address that needs the server at identification services coordinator place, and the server that no longer needs to know active service has many.
With the same in the previous embodiment 2, memory transactions equipment can be set between server and array.
In the present embodiment, the importance of Differentiated Services device not, service can be switched between each server, and for example, it is to carry out according to following principle that the service that each webmaster processing module provides is switched between described each NM server:
The service arrangement that different webmaster processing modules are provided is in different processes, and the service that may cause handling the same class processing module of bottleneck provides is separated in the different processes, reaches like this to avoid or to reduce the purpose of handling bottleneck.
The Disaster Tolerant Scheme of more reasonable distribution physical resource, and support N+M mode.
Can increase the managerial ability of network management system by increasing server and memory space mode equally.Use this embodiment, the function of previous embodiment does not reduce or weakens.
In sum, adopt many NM servers to form an OMC of operation maintenance center in the distributed network management system that the embodiment of the invention provides, the network element that OMC can be managed constantly increases along with the increase of number of servers, can manage ultra-large network.Dilation process only needs to increase server and storage, makes dilatation more level and smooth, has simplified engineering construction, has saved once more operations such as north orientation butt joint one cover independent O MC, has reduced the complexity of dilatation and the time of engineering construction and test.Dilation process does not need to replace existing hardware, has saved hardware cost.Single cover OMC centralized management, operator's demand side be to the management that can realize cover OMC Internet resources, thereby saved management cost and engineering maintenance cost.
